I purchased a refurbished Note 9 from Amazon and it works well. However, the phone was originally sold in Korea, but I live in the US. As such, the phone has some issues. One being there is no visual voicemail app, and trying to install it gets denied. Another is that I cannot use Samsung Pay. I would like to flash the phone so that it is set to the US region, but I can no longer find info on how to get that done. TIA for any help.
